Abstract: TWO-WAY PLUGS FOR WELLS            ABSTRACT          A plugging device is described for installation as by wireline tools in a receptacle in a well flow conductor for plugging the flow conductor against flow from below as well as from above.  The plugging device includes a tubular housing (100) having seals (76) for sealing with the receptacle and lock members (74) for anchoring it therein.  A mandrel (104) is reciprocable in the housing between lower and upper positions for moving the lock members to locking position and for allowing them to move to unlocking position.  A plug member (102) closes the housing and is movable relative thereto between lower and upper positions and there is a locking mechanism for locking the plug member to the mandrel whenever the mandrel is in its lower position and the plug member is moved to its upper position to prevent the mandrel from being moved to its unlocking position.  A running tool is provided for installing the plugging device which will not release the device unless it is properly installed in the receptacle.     (Figs. 4A & 4B)

Title: Composite brake drum with improved locating means for reinforcement assembly
Inventor: RAITZER DONALD A
IPC: B22D19/02
Filed: 1991-04-11
Granted: 1997-08-26
Abstract: A composite brake drum particularly adapted for motor vehicle applications.  The brake drum includes a reinforcement assembly embedded within the cylindrical portion of the drum.          The reinforcement assembly is preferably made from steel wire stock and includes a plurality of circular loops spaced axially within the brake drum cylindrical portion.  Axially extending locator wires  are mechanically  fastened to  the  reinforcing loops and serve to locate the loops.   End portions on the locator wire contact only one of the mold halves forming the mold  cavity  and  enable  the  device  to  be  essentially self-locating without crossing the parting line of the mold.          By not crossing the parting line, the position of the loops is maintained within acceptable tolerance limits from the finished friction surface of the drum.   The composite brake drum is fabricated by pouring  molten  iron  into  the mold  and  then performing finish machining operations.

Title: Artificial intelligence pattern-recognition based noise reduction system for speech processing
Inventor: GRAUPE DANIEL
IPC: H04B1/66
Filed: 1992-03-06
Granted: 1997-10-14
Abstract: A system is provided to reduce noise from a signal of speech that is contaminated by noise.   The present system employs an artificial intelligence that is capable of deciding upon the adjustment of a filter subsystem by distinguishing between noise and speech in the spectrum of the incoming signal of speech plus noise.   The system does this by testing the pattern of a power or envelope function of the frequency spectrum of the incoming signal.   The system determines that the fast changing portions of that envelope denote speech whereas the residual is determined to be the frequency distribution of the noise power. This determination is done while examining either the whole spectrum, or frequency bands thereof, regardless of where the maximum of the spectrum lies. In another embodiment of the invention, a feedback loop is incorporated which provides incremental adjustments to the filter by employing a gradient search procedure to attempt to increase certain speech-like features in the system's output. The present system does not require consideration of minima of functions of the incoming signal or pauses in speech. Instead, the present system employs an artificial intelligence system to which is input the envelope pattern of the incoming signal of speech and noise.  The present system then filters out of this envelope signal the rapidly changing variations of the envelope over fixed time windows.

Title: Shoe tongue construction
Inventor: HILL I DAVID
IPC: A43B23/26
Filed: 1992-01-07
Granted: 1996-12-03
Abstract: This disclosure is directed to a novel shoe tongue construction wherein the tongue is made as an integral extension of preferably the heel portion of the shoe.  The tongue may also be an integral extension of the quarter.  The tongue construction provides greater comfort to the wearer of the shoe than do conventionally mounted tongue constructions because the tongue is integrally formed with either the counter or the quarter of the shoe rather than being stitched to the vamp.  This construction is also more economical to make because cutting and stitching requirements are reduced.

Title: Method for producing protein microspheres
Inventor: MATHIOWITZ EDITH
IPC: A61K9/16
Filed: 1990-11-06
Granted: 1997-02-04
Abstract: Protein microspheres are formed by phase separation in a non-solvent followed by solvent removal. The preferred proteins are prolamines, such as zein, that are hydrophobic, biodegradable, and can be modified proteolytically or chemically to endow them with desirable properties, such as a selected degradation rate. Composite microspheres can be prepared from a mixture of proteins or a mixture of proteins with one or more bioerodible polymeric materials, such as polylactides. Protein coatings can al-so be made. Compounds are readillly incorporated into the microspheres for subsequent release. The process does not involve agents which degrade most labile proteins. The microspheres have a range of sizes and multiple applications, including drug de-livery and delayed release of pesticides, fertilizers, and agents for environmental cleanup. Selection of microspheres size in the range of less than five microns and mode of administration can be used to target the microparticles to the cells of the reticuloend-othelial system, or to the mucosal membranes of the mouth or gastrointestinal tract. Larger implants formed from the micros-pheres can also be utilized, especially for agricultural applications.

Inventor: CASEBOLT SCOTT C
IPC: F16F7/00
Filed: 1992-08-24
Granted: 2002-04-30
Abstract: The shock absorber disclosed herein includes an elongate strip of a webbed material or fabric. Both ends of the fabric are cut a short distance along the longitudinal axis of the strip of material, and then one end of the strip is twisted a half turn, or 180°. The two ends of the Webbing are brought together, and the juxtaposed halves of the separate ends may then be folded back on themselves and sewn together to form a loop. One loop may now be fastened as by a safety hook to a worker's safety belt or harness, and the other end fastened as by a double locking snap hook to a rope or cable attached to a fixed structure such as a building or scaffolding. The excess length of webbing may be folded back onto itself until it fits compactly into a housing or casing. The housing or casing must be releasable so as not to interfere with the tearing action of the strip of webbing should the worker fall off the structure to which the shock absorber is attached.

Granted: 2004-02-24
Abstract: A process is described for the elimination of hydrogen sulfide from gas mixtures by catalytic oxidation over activated carbon catalyst which converts the hydrogen sulfide to elemental sulfur and water, the former being sorbed by the activated carbon while the latter is transported with the gas mixture and may be removed by known dehydration processes. The above oxidation process is conducted at elevated temperatures and pressures and with sufficient residence time to assure virtually complete conversion of the hydrogen sulfide with minimal production of by-product sulfur dioxide. Traces of heavy hydrocarbons in the feed gas mixture which may reduce the life of the catalyst and the quality of the sulfur product may be removed by cryogenic means or by sorption on an activated carbon guard bed. Both the activated carbon catalyst used to oxidize the hydrogen sulfide and the activated carbon used to remove heavy hydrocarbons from the feed gas may be regenerated by passing inert gas or product gas through the beds of these materials at elevated temperatures for sufficient time to remove the sorbed sulfur or the heavy hydrocarbons, respectively for use as by-products of the process.
